BTW. Just to avoid any confusion, if you add up all your ages I probably still beat ya'

The board arrived!!! Now if I could just get those freakin' parts in :cautious:

Age discrimination is a bad thing. . . . @vigilante398 will know what I'm talking about ;)

I was researching about signal caps only to discover that there IS a polarity to non-electrolytic caps. Apparently there is. . . . inner foil-dielectric layer-outer foil. . . the outer foil functioning as a shield similar to audio cables. The lead coming off of the outer foil should be...

So Nathan. . . you're a Matchless fan. I've never messed w/ 'em. Does the EFtrot give off that Matchless vibe for you?? If running thru an IR what type of speakers do I want to emulate, what typically goes in a DC30?

Go here for tubey goodness. . . . CLICK HERE

AND @Mike McLane IS VERY HAPPY. WAITING FOR MY PA (DEUX) TO ARRIVE IS WORSE THAN AN 8-YEAR-OLD WAITING FOR SANTA!!!!!!!!

Get on the SushiBox FX thread and check out the Echo Foxtrot for a simple clean TUBE driven preamp. It's got a EF86 preamp tube which is not a Fender approach. . . . BUT. . . . if you can wait I know that Nathan is working on a DIY blackface Fender preamp that I expect (hope) is not too far off...

Ah, replace the 220K w/ a 250K trimmer!?!? Good idea! Sometimes I'm slow on the uptake. Unfortunately I don't think there's enough real estate on the HV board to insert the Trimmit.

Tie the 4K7 & 220K vertically and install a 1K trimmer. Just clip the pin on the "220K side" and instead jumper that eyelet back to Pin 2? For that matter, would the slight add'l resistance created on the "220K side" by installing per plan just shift the "balancing act" slightly, but still...

I know space it at a premium, but the trimmer is UBER sensitive up in the desired range. If you use 4K7 as a fixed value and "bias" it by varying resistance to GRD would there be any value to shoehorning a 4K7 somewhere on the board in series with the 220K (or does somebody make a 225K?) and...

(y) Now all I have to do is get those two 1M pots I FORGOT to order 😵‍💫. All dressed up and nowhere to go!!!

Why can't they just make this simple!!!!!!! :ROFLMAO: Good info. . . thx!!

I figured that from looking at the Space Heater schem & assuming that 250vdc +/- was what you were going for there. As a learning opportunity. . . . 4K7+560 = 5,260 (71% + 29% = 100%). If I wanted to vary the HV is this a linear relationship that I can use to calculate other desired values...

So the points I'm describing are both on the "HV rail side" of the respective components with no other components in the path?

I have rebuilt my Space Heater starting with a new board. After soldering and cleaning I examined the board for possible solder bridges and I once again hit upon this guy and sure enough get continuity across the solder joints. . . . I could swear that the two solder joints are not...

Sounds pretty good. Actually, I sent it to a friend who is a professional player who is running it through its paces running through a PowerStage 170. If it passes initial muster he's going to try a couple of gigs with it. . . says that's the only way to see if it REALLY works. Anxious to...

I thought I saw a comment from Chuck Bones many moons ago re: a level of caution using any ol' computer laptop PSU for these. Is this simply a matter of having plenty of current to deliver that extra umph when needed? Are there any guidelines we can look to in purchasing an adequate PSU? How...

Roberto, when we gonna see a proper TPA3118 PCB? Inquiring minds want to know. :rolleyes:

Will do. (y)
